Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

    WIsh I could tell if you worked...

    By CatLover on Mar 11, 2021

    Unfortunately, the can I received must have been defective, since all it seems capable of doing is shooting clumps of poison whipped cream everywhere. Not sure how I'm supposed to use this if I can't spray it on anything; I was super excited to use it since my house is mostly hardwood and I was seeing reviews saying this was good for that, but I don't want to take my chances re-ordering.

    Did what it said

    By obxstargazer on Jan 20, 2021

    Vet recommended for a critical flea problem I had in house carpet. Had all stages of fleas which I didn't realize. Thought I'd handled prior, using other sprays & products but none of them completely killed all fleas. This got rid of them in hours to overnight. Vet said reputable company, product does the job as it works on all stages of fleas, & for 7 mths Use Caution about fumes. they're very harmful to pets w/out you realizing. Make sure "all pets" are out of house or in very safe enclosed place where spray is not used. Ventilate, wait at least 2 hrs & longer if possible before returning them. .

    Excellent when used with Capstar

    By vedawms on Dec 30, 2020

    My mobile veterinarian accidentally unleashed fleas in my home. Now, if it looks like my cats are scratching, I give them a dose of Capstar each. (Not a poison like most flea meds.) The flea free effect of Capstar only lasts 24 hours, so you have to spray the house with Virbac right away (while the cats are locked in the bedroom or bathroom). It only takes about 30 seconds to spray down my entire living room. There is no odor, and it dries in about 20 minutes. Be aware that it will make linoleum VERY slippery, but it's fine after it dries. It hasn't damaged any fabrics. Once it dries, I let the cats out, then spray the bedroom. I spray it on the floors, on pillows, and the sofa -- My mobile veterinarian accidentally unleashed fleas in my home. Now, if it looks like my cats are scratching, I give them a dose of Capstar each.

This combination of tactics has been a godsend! No more fleas!! No more sick cats!! I will never use Advantage, etc., or bug bombs again. … more

    Recommended by my Vet

    By Carole on Dec 13, 2020

    Extremely effective for a flea infestation. I used it on carpeting exactly as directed. The can says it covers 2,000+ square feet. I barely got three rooms treated when the can was empty after approximately 400 square feet.) I did order another can to finish the job. After two hours it's dry and you can vacuum. I continued to vacuum daily to remove any remaining fleas, eggs, etc. After about a week, no sign of the fleas. (I was also getting bites and that stopped, too.) Important...remember to also apply a flea treatment to all of your pets. I would recommend this product even though it's pricy. I only gave it a "4" instead of "5" because of the volume in the can.

    This works perfect.

    By coyotepup on Jan 16, 2021

    When you have tried everything with partial results, give this product a try and the problem is resolved. Note: once you figure the square footage of product needed, buy an extra can or two as you may end up spraying more than needed for your own assurance. I assure you, this product works perfect.

    Traded one mess for another

    By Human on Dec 4, 2020

    So far, this product seems to be helping, but the fleas are not totally gone yet. I'll do a second round of treatment in a week or so. However, even when following the directions on the can, this stuff comes out in big, wet blobs that create a giant mess. It's like spewing poisonous whipped cream everywhere. I have found no indication of what angle the can should be held at when spraying, but I was not able to get a consistent spray.

    ACTUALLY WORKS

    By mehrylie on Nov 29, 2020

    I have tried four different flea sprays before a friend recommended this one to me. We struggled with fleas for MONTHS. After so much guilt for my pets suffering, we tried this as a last ditch effort before we called in an exterminator. Worked after just ONE use. Took my pets to a friends for the weekend, sprayed half the bottle around the whole house, vacuumed, and we have never needed to spray again. HIGHLY RECOMMEND. You need this.

    Works good

    By Alyssa on Jan 2, 2021

    Works great when spraying on present bugs but definitely doesn't seem to be keeping the bugs away or killing any bugs that come into the area where the product was applied.

    LOVE IT SO MUCH!!!

    By Stevie on Oct 6, 2020

    We’ve been battling a flea infestation that came on so sudden about a month ago. We tried sprays and bathing them once a week, Terminix came out and sprayed and still nothing was slowing them down. I used this and within 24 hours there were barely any active fleas. I sprayed again this evening and I’m betting we won’t have any active by this time tomorrow. This was LITERALLY A GODSEND! We’ve been boarding our cat and dog and I called today to extend until we can 100% be sure they’re all gone before bringing them back home! We also sprayed our yard to cover all bases!
